,Apparatus'for Storing and Dispensing Icefollowing is a specifiv ream, of cation. 1

This invention relates to apparatus for storing and dispensing ice cream, ices and the like,the object being to construct a mathis character so that the ice cream touchedby the hands of which the the dispenser.

Another object is to provide a machine of this character in which a collapsible container made of paper or similar material, is thereby re ingwhich often'results Where the cream is placed in a metal container and allowed to remain in such container until acids in the fruit extracts used in flavoring the'ice cream have begun to attack the said metal container.

Another object is to construct a machine of this kind-in such I a way that the ice cream placed in the machine may be left unflavored until the customer has designated the particular-flavor he wishes, at which time the portion ordered by the customer is fed from the machine and flavored with any deslred flavoring from the large assortment of fruit and flavoring syrups which the confectioner usually has.

A further object is to'so construct a machine of this kind that the ice cream can be kept at the desired hardness, at the same time a big saving. being effected in the amount of iceused for refrigerating the cream.

A 'further object is to construct a machine of this class that will automatically deliver the exact amount'of cream desiredbv the operation of one of a series of handles: A still further object is to construct a machin'e of this kind that will handle the ice th air from the time i i pl ced cream in a thoroughly sanitary and cleanly manner, without permitting the we cream or flavoring syrups to come in contact with in the 1111b" chine until it is ready to serve to the customer and saving the loss which always eX- ists when the me cream is handled in the ordinary way and dipped from the can each time a sale is made.

With these objects in view the invention Patented Apr. 1,1919.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

The housing or casing of my machine is substantially rectangular and is formed of spaced sheet metal walls 1 with cork, min

eral wool or like insulating material 2 packed between the said sheet metal walls thus forming an eflicient nonakinductor ofheat to prevent the interior of the machine from becoming warmed bythe surrounding. atmosphere. Within the insulated box thus f formed. is alaterally extending sheet metal wall 4 which is spaced from the'rear wall of the machine and extends from the upper in- 'Lerior wall downwardly, and thence rearwardly -as at 5, thusforming an upper rear compartment -6 within the box. Spaced. slightly forwardly of the wall 4 is a sec ondlatcrally extending wall 7 which termi --mates as shown intFig. 3 at a point a few inches distant from tl e end walls. 1 A transverse wall 8 extends oi wardly from the ex.

1 receive the screw 28. A series of holes 38 treme left end' of the Wall '7 and connects to the front wall of the box and a similar .wall 9 extends from the extreme right end of the wall 7 to a partition wall to be hereinafter more fully described. Intermediate the walls 8 and 9 is i -third transverse wall 10 which extends from the wall 7 for-' wardly to tha front wall of the box, thus forming a compartment 11. The walls 7, 8 and 10 extend from the floor to the inside of the top of the box. .A horizontal wall 12 soldered or otherwise secured to the walls 7, 8 and 10 and the front wall of the box forms a lower compartment 14 directly beneath the compartment 11 all of which is clearly shown in Fig. 4. Spaced slightly from the wall 10 is a lateral wall 15 which extends forwardly from the wall 7. Innnediately adjacent the walls 7,9 and 15 is a- -vertical casting 17 having a door l8hinged at 19. The door 18 is "grooved as at 20, Fig. 1, the said grooves being adapted to fit snugly upon tongues arranged upon the forward edges of the side walls of the casting 17 so that when the door 18 is raised into vertical position anair tight joint is efi'ected between the casting and the said door which thus forms, with the three sides of the casting, a vertical compartment 21.

\ The upper edge of the casting 17 has a tongue. 22 formed thereon, the said tongue fitting withiira groove upon the under edge of a casting 24., Land 8. -The front and rear walls of the casting 2-4 extend vertically from the casting 17. The side walls,

however, are inclined slightly toward the center and terminate in a laterally extending cylindrical portion 25. which is inclined slightly downwardly toward the front end. A thin sheet of non-corrosive metal is applied to the entire interior of the castings 17 and 2+ and the door 18.-

The lower end of the compartment 21 formed by the casting 17 has fitted therein a vertically movable plunger 26 which has a centrally located downwardly projecting collar 27. The collar 27 is internally threaded and is adapted to receive the upper'end of a vertical screw 28. A bracket 29 secured by bolts 30 to the under side of the machine. has a central]aperture' 31 drilled therethroughe thrygh which the screw 28 is adapted tosli e. A ball race 32 is formed on 't'lie'ljlpper side of the bracket -2l l and ;1. similar ball race 34 is formed on the nnder side of a plate. 35 which is secured tTPthan nder..sideoi l lie machine by the bolts 30, bevel .gea'rJ-Bll mounted to rotate upon ball bearings located within the races 32' and 34 just de\ scribed, is internally threaded as at 37 to is drilled in the plunger 26, lhe said holes being adapted to receive; pi11s. fjv l 1icli ,ex-

.tend downwardly froni'if'swondary. plunger 40, the said secondary plunger being spaced slightly above .the. plunger 29 and fitting snugly within the compartment 21. Coiled springs 41 are interposed between I the plunger 26 and the secondary plunger and are held in position by thepins 89 as shown in Fig. 7. Spaced slightly to the left of the vertical screw 28 is a bearing 42,

Figf l, which is bolted to the plate 35 and *With. a similar bearing 44 is adapted to haverotatably mounted therein the hori'-' zontal shaft 45. Keyed to one endof the shaft 45 is a beveled pinion 46 which meshes with the beveled gear 36, the opposite end of the shaft 45 having keyed thereto a sprocket 47.

, In substantialvertical alinement above the shaft 45 is a stub shaft 48 journaled in a bearing secured to the outside of the left hand end wall of the machine. Thestub shaft 48 carries a sprocket 49 over which passes a sprocket chain 50 which also connects to the sprocket 47'. Secured upon the shaft 48 adjacent the sprocket 49 is a gear 51 which meshes with gears 52. and 54, the gear 52 being carried by a stub shaft 55 which in turn is'carried by a bearing mounted upon the outside of the'e'n'dwaIl of the machine in direct vertical alinement above the shaft 48, the car 54 bein carried by asimilar stub sha 56imounte in a journal in direct vertical alinlement beneath the shaft. worm gear 57 is also mounted upon the shaft '55 and a s'imilar'worm gear 58 is mounted upon the shaft '56, and a worm 59 formed on a sleeve 60 lies between the worm gears 57 '1 and 58 and is adapted to normally'remain out'of engagement with both 'of thesaid rod 61 opposite the one entering the worm, carries a pin on which is mounted a roller. 60'

'worm-gears'. A rod 61, Fi 2 and 8, enters one/end of .the worm 59 an has secured upon it by a set screw, an annular collar 62, whichis which shaft has an eye portion 70 fittedabout' the shaft67 adapted'to rock thereon. I It is thus seen that the sleeve 60 carrying the worm 59 and the pinion is freeto turn upon the rodsj6l and the shaft 69 and at the same time can be rocked into engagement with either of the worm gears 57 or 58 by virtue of the eye 70 fitting about the shaft 67. The endofthe 71, the said roller engagin asubstantially V-shaped bracket 72' whic is mounted on the front wall of the machine and off-set as shown in Fig. 3to come into alinement with the said roller. A bifurcated arm 74 is mounted to swing upon a 7 secured in the side wall of the machine and has its bifurcated end straddling the rod 61 and held in engagement with an enlarged portion 76 upon the said-rod 61, by means" of a leaf spring?! which istensioned by a set screw 78. An operating handle 79 mounted to a swing upon a pin 80 secure in the side-wall of the machine, is connec d to thepin carrying the roller 71, secured in he rod 61, by

a rod'Sl.

The arm 74 undertens'ion the spring 7 7 I will through its engagement with the en:

larged portion 76 upon the shaft 61, normally hold the'roller 71"within the point of the V of the bracket 72, at; which time the rod 61 assumes a 'perfectlvhorizontal posi M tion, since the point of the V is in direct horizontal alinement with the center of the stub shaft 67'. The worm 67 is thus held out of engagement with either of the worm gears 57 or 58. The depression'ofthe operating handle 7 9 willcause the roller 71 to travel downwardly upon the inner face of the lower section of th'e'V-shaped bracket 72, thus causing the shaft 69, the worm 59 and the rod 61 to pivot upon. the shaft 67 and bringing the worm 59 into engagement with'thefworm gear 58'. It is obvious that the pinion 65 will in the 'mea'ntime'remain in constant mesh with the pinion 66. Should the handle '79 be lifted instead'of depressed as just 'described the roller will travel upon theupper section of the" V shaped bracket causing the rod 61 andthe' worm 59 to pivot uponfthe shaft 67 and bringingthe worm into engagement with the warm gear 57.

Mounted to 'i'otate upon the shaft 67 is a worm gear 82, which meshes with 'a worm 84 secured upon-the drive shaft of an electric motor. '85, which is'woundto rota e clock:

wise. The end of the shaft 67 is threaded as shown in Fig.8 to receive an adjusting nut spring 87', interposed between the said 'nut and a'bearing plate 88. Ball bearings are interposed between the bearing plate 88 and the worm gear 82. Suflicient tension can therefore be "put upon the spring 87, .to

bring the inner-face of the gear 82 in: contact with the face'of the pinion 66 to cause the said pinion'to be rotated with the gear 82'fthrough frictional contact therewith. f

Formed integralwithl'the pinion 66 is a sprocket 89 over which passes a sprocket chain 90, which extends upwardly and over a' ,86 which is designed to tension a coiled sprocket 91, rotatably mounted upon a shaft 92. Formed integral with the sprocket 91 is a sleeve 94 in which is formed an annular groove 95, which is adapted to receive the inwardly projecting pins carriedby the bifurcated end .of-a bell crank lever 96 mounted to rock within the bracket 97 secured to the side wall of the machine (see Fig. 15).

The upper end of the saidhell crank leveris also bifurcated and is secured to the end of a sliding rod 98. One member 99 of a clutch is also formed integral with the sprocket 91 and a coiled spring 100 is adapted to exert an inward pull upon the upper end of the bell crank lever to normally hold the member 99 of the clutch out of engagement with the opposite member 101 of the said clutch, which member is keyed or otherwise secured to the shaft 92. I 1

Referring now particularly to Figs. 1, 3 and 5, a series of handles is indicated at 104, 105, 106 and 107 and beneath each of the said handles is a plate 108 bearing figures rods 109 being free to rotate within the said tubes. Secured to each of the rods 109 at its extreme rear end is a disk like member 111 which "has an off-set ear112 and oppositely disposed pins-114 and 115. The disk portions 111 are adapted to normally stand with the pins 114 slightly to one side of the vertical center at the top of the said'disks and with thepins 115 standing slightly to the other side of the vertical .center at the bottom. Eyes upon one of the ends of rods 116 are fitted over each of the pins 114, the opposite end of each of said rods being formed into an elongated eye 117 fitting over a stud 118 fixed to the upper end of a bell crank lever 119, which lever is pivoted at 120 and has a roller 121 journaled between bifurcations formed at its lower end.- Eyes u mnone' of the ends of rods 122 are fitted over each of the pins 115, the said rods 122 beingsubstantially similar to the rods 116 and terniimtting at their opposite ends in elongated eyes 124, which eyes are adapted to receive a pin 125 carried by a second bell crank lever 126, pivoted at 127, and having a roller 1 28 journaled between bifurca tions at its lower end. .The rod 98 previously described and having its outer end pivoted to the upper extremityof the bell-crank lever 96, extends through the end wall of the machine and receives a stud 129 secured in the bell crank lever-126.

Coiled springs 130 are secured at their lower ends to each of the pins 115 and at their upper ends to studs fastened to the inner rear wall of the machine. A spring 133 se cured at one end to the inner end wall of the machine and at its "other end to the bell crank lgver 119 is arranged to exert a con supported at one end upon a pin 132 designed to move vertically within a slot 134 in the upper end of a supporting bracket 135 secured to the inner wall of one end of the machine. The opposite end of the rod 131 is supported by a coiled spring. 136 secured to the inner wall at the other end of the machine. Rods 137 and 138 also extending transversely of the machine are fixed at one of their ends in the. supporting bracket 135 and at their opposite ends in a substantially similar bracket 139. A hollow rectangular traveling carriage 140 is formed with horizontal ears 141 and 142 extending across its rear side, the said ears having longitudinal apertures therein through which pass the rods 137 and 138 respectively, the said rods 137 and 13S forming a track upon which the carriage 140 is adapted to slide. Apertures are formed. in the top and bottom portions,

of the carriage 140 to receive a bolt 144, the

said bolt having a worm "engaging portion 145, at its lower end and being bifurcated at its upper end to receive a roller 146. Lat

orally extending ears 147 formed on opposite sides of the .bolt 144 are normally held in contact with the top of the. casing by means of coiled springs 148 within the'said casing. The roller 146 is adapted to engage the'lower sideof' the rod 131. A stop 149 isffastened upon the rod138 and'c'a'ri ies an idler pulley.

150 over which passes a' flexible cable 151 s eeured atone end, to the carriage'140 and with y a wcight'152 operating in 'agui'de 154 secured to its other end. The'shaft 92 previously described extends, within the :.a-

chine and is journaled at one end in the supporting bracket 139; and near its other end in the bracket 135 and for substantially its en- ..tirelength within the'said machine is fashioned to form a worm -'as clearly shown in, F 1g. 6.

It will now be seen that when one of the handles 104,105, 106 or 107 is moved in the direction indicated by the arrows in Fig. 1 the disk member 111 secured by its rod 109 to the said handle will be moved in the directionindicated by-t-he arrows on Fig. 6, thus moving the ear.112- upon the disk portion to a position at the vertical center beneath the rod '109. At the same time the rods 116 and 122 connected-to the'disk 111 which pull upon the disk mei'n'her in the opposite directions. holding the said disk member in this position after the handle attached to its rod 109 has been released. The bell crank lever 126 having been'rocked as just described will cause the rod 98.to rock the bell crank lever 96, thereby moving the memshaft 92 will- .begin to rotate. This depression of the rod 131 by virtue of its contact with the roller 146 carried by the bolt 144 forces the wormengaging portion 145 of the said bolt into engagement with the worm upon the shaft 92. Rotation of the shaft92,

through the engagement of the Worm upon the said shaft with the worm engaging portion .145, will, therefore, cause the member 140 to be moved along the rods 137 and-138 toward the opposite end of the machine. When the member 140 reaches the point on the rods 137 and 138direct1y beneath the disk member 111 which has been moved, the roller 146 will contact with the ear 11 2 upon the said disk portion until the pin ,115 has once more passed vertical center at the bottom when the spring 130 attached to the said pin will again be pulling upwardly from the 'OPPOSltO side restoring'the disk to normal position. It is obvious that the rods 116 and -'122 which had been operated to rock the bell crank levers 119 and 126 respectively will have now released their pull upon the said The spring 133 attached to the lever 119 will therefore restore the said lever to normal position and allow the spring 136 to lift the end of the rod 131 to which it is attached. In the same manner the spring 100 attached to the lever 96 will swing the said lever back to normal position, disengaging the clutch members 99 and 101,

forcmg the rod 98 inwardly and restoring the lever 126 to normal position, thereby al' lowing the bolt member 144 within the carriage 140 to be forced upwardly by the springs 148 and lifting the rod 131 to normal position. The raising of the bolt member 144 will disengage the portion 145 from the worm on the shaft 92 and allow the weight 152 on the cable 151 operating over the pulley 150 to pull the carriage 140 back to normal position against the stop 149.

In, directhorizontal alincment with the 5 shaft 92 is a shaft 155 which is journaled torotate in the brackets 135 and 139, a gear 56 mounted upon the said shai' 155 meshing with a gear 157 mounted upon the shaft 192, thereby causing the shaft 155 to rotate in the opposite direction-of theshaft 92. worm 158 is keyed to the shaft 155 and meshing with thesaid worm is a worm gear 159, keyed to a shaft 160 which extends centrally through the inclined cylindrical por tion 25 at the top of the casting 24. A worm conveyor 161 is fonned upon the shaft 160 and is adapted to rotate with the said shaft.

lhcforward end of the worm conveyor fits within atubular portion 162. The said tube is secured at one end to a wall 164 \VhHll is soldered lorbtherwise secured to form awater-tightjbint upon the casting 24, the

. bottom of the 'by means of a rod 188 and is A swung inwardly toward the machine to cause the knife shown in Fig. 4, and being soldered thereto I r to form a water-tight joint. The bottom of .the compartment 165is in a horizontal plane slightly above the top of the casting 17 The lower portion of the front wall of the casting 24 has an off-set 166 as shown in Fig. .13 and an aperture 167 is formed in the inclined portion 168 connecting the said offset with the vertical portion of the casting above'the off-set. The aperture 167 is formed to leave radial spoke-like portions extending toward the center of the said. aperture to form a bearing for thevalve stem 169 of the valve 170. A bracket 171 is secured to theouter side of the casting and interposed between the said bracket and an annular flange formed upon the valve stem 169 is a coiled spring 172, which is adapted to normally hold the valve unseated to leave the aperture'167 open. A recess 174 formed in the front wall of the machine is inclosed by the upper wall 175 and end walls 176 and 177, the bottom wall178 of the said inclosure being in horizontal alinement with the metal box-like member 165, the rear wall 179 of this compartment being secured to the front wall of the compare ment .165. A cutoff block 180, with a central aperture 181therethrough is secured to the wall 179. The aperture 181 is of the same diameter'as the inside diameter of the tubular portion 162, the said aperture being adapted to register portion and having a plurality of hexagonal tubes 182, Fig. 14, forming a honeycombed' portion within the said aperture. The front face of the cut-off block 180 is cut at an angle with the said tubular and has grooves formed by flanges 184 exformed by the flanges 184 and centrally located upon its inside edge is a substantially crescent shaped knife 186. An operating handle 187' is pivoted to the side of the machine and connects with the sliding plate adapted to be 186 to pass in front of the aperture 181.

Located within the compartment 11 is a plurality of containers 190. the bottoms of which are inclined downwardly. toward" the front side as shown in Figs. 5 and 12.v Each of the said containers is designed to be filled with a difl'erent flavoring syrup and has a forwardly projecting tubular portion 191 connected to its lower front corner. An aperture-192 communicating with the said tubular portion is normally closed by a valve 194 under the'tension of'a coil spring 195. An operating handle 196 connects to a plunger 197' within the tubular portion. Theplunger' zle 201 and a valve 202 located in the outlet pipe is designed to open at the'outward v stroke of the plunger. It will thus beseen that the first outward stroke of the plunger will unseat the valve 194 drawin a charge of the flavoring syrup into the tu e 191, the valve 199 meanwhile remaining positioned to close the aperture 198. At the first inwardstroke of the plunger the valve 194 is seated preventing the syrup between the plunger and the said valve from returning to the said container, the valve 199 unseating to allow the syrup to passthrough the aperture 198 as the plunger moves backwardly. At the next stroke forward of the plunger the valve 199 is again seated and the valve 202 is opened allowing the syrup which was first pumped into the tube andnow lies in the said tube between the front of the plunger and the forward end. of the tube, to co forced through the outlet pipe 200, the valve 202 and through the perforations in the nozzle 201. A new charge of syrupis meanwhile being sucked through the valve 194' so that each succeeding forward stroke of the plunger will discharge a v quantity of syrup through the nozzle 201. Connected to each of the syrup containers 190 by a pipe 204, is a; storage tank 205, containing the same kind of'syrup as that in the syrup container, to which it is attached. The pipes 204 extend almost to the bottom of the storage tanks 205 and a second pipe 206 terminating ashort distance above the end of the pipe 204passes' outs wardly through the top of the said storage tank and into an air washing tank 207. The said air washing tank isfilled with any suitable solution for purifying the air as it passes therethroug'h to a point just below the .end of the pipe 206 and a pip'e'208 reaching almost to the bottom of the air washing tank. extends through the cover thereof to permit air to be sucked in. The. covers to the storage used to displace the syrup pumped-from then" tanks 205 will necessarily haw .o be secured an' air tight manner as will also the con-u to the air tank.207. A suitable connection- M will be located in each of the pipes 204 to dis- 5 v connect any of the storage tanks when it be comes necessary to refill the same. By this.

arrangement itwill be seen that all of the air storage tanks'will be purified'by passing through the air washing tank, thusinsuring absolute sanitation...

ing 225 is formed in the wall of the. compartment 11 in which are located the syrup conoutlet pipe 228 in wh Mounted upon the shaft 92- the gear 157 is a cam 210 which is designed to operate between the lateral extensions 211 and 212 of a rod 214. The said'rod extends downwardly and through the guide tube 215 and is connected at its lower extremity to the plunger of a force pump 216. Inlet ports 217 are formed in the cylinderof the said pump and an outlet port 218 connects with a pipe 219.. A spring seated valve 220 is ar ranged to open at the down stroke of the plunger and close at its upward stroke. The

ipe 219 extends laterally to a point slightly eyond a vertical line drawn downwardly from the center of the casting 24, and thence upwardly to substantially the top of the in- 30 side of the machine where a 'U-fitting connects the upper end of saidpipe with a pipe 221 extending downwardly within the wall 164, The pipe 221 extends as shown in Fig. 9 to approximately the bottom of the wall 164. A second pipe 222 shown in dot and dash lines Fig. 4 extends upwardly from the diagonally opposite bottom corner of the wall 164 and has a U-connection at its upper end which enters the compartment formed by the wall 165 and the wall of the tank 164, whereit connects to a downwardly extending pipe 224 which reaches alinostto the bot.- tom of'the second tank. An over-flow open- ,ment 165 at the diagonally oppos pte upper corner to the one into which the ipe 224 discharges. A pipe 226 extends upwardly from approximately the bottom of the com-' partment formed by the wall of the box-like structure 165, the end and front walls of the machine and the partition 10 at the end opposite the one in which is located theoverflow opening 225, the said pipe extending through the wall 10 and into thecomparttainers 190. An outlet locatedin the wall9 at approximately the diagonally opposite corner from the pipe 226 in the com artment 11, connects with a drain pipe 22 which 1 0 extends thence downwgrdly and to a sewer i h is located an ordinary U'-trap 229. l c

The space surrou'ndihgthe compartments 11, 14, and the'casting 4, can be filled with chopped ice as indicat d'ir Fig.1 3, the ice- .being' packedwithin th said space with ordinary salt in the man er now employed to pack ice cream.. It isolf course'umlerstood that the compartmentG formed in'tthe upper 12o rear, corner of the machine by [the walls 4 and 5 will not be filled with ice. Thebrine n 6 formed by the salt and melting icewill ac- 'cumulate in the bottom of the machine'be neaththechopp'ed ice and at each engage- 1 25 ment of the clutch member 99 and 101 which a ts, in m tion" the shaft- 92, the cam 210 inounted upon the said shaft will, through its engagement withfthe arms 211 and 212 on the plunger rod 214, cause the plunger within the pump 2,16/to/ be reciprocated. Each upwardstrok rgof the plunger will admit brine'through the inlet ports 217 to the cylinder of thj pump and each downward stroke of the'plunger when it reaches a oint'ibelow the'inlet ports will force the rine through the aperture 218 and, past the valve 220 and into the pipe 219 whence it travels upwardly and is discharged through the pipe 221 into the'bottomof the tank 164. Rising in this tank to the level of the U-connection between the pipes 222 and 224, it will overflow into the compartment formed by the wall 165 where it again rises to the level of the outlet 225 and is discharged into the next compartment The pipe 226 in turn carries the brineinto the compartment 11 Where it rises to the level of the outlet to the pipe 227 whence it is discharged. to the sewer; It is thus seen that a circulation is. maintained so-that even though.

.a. largepercentage of the ice originally placedin the mac ,ine for refrigerating purposes has melted, leavingthe ice space in the upper partof the machine empty,-the

. cold brine from the bottom of the said space A will be circulated through the machine to maintain an even refrigeration.

Referring now to Figs. 4 and 7, one contact member 230 of a switch is shown secured to the under side ,of the secondary plunger 40.-

' The opposite contact member-231 of the said of the bottom of the 'machine. Circuit I switch is secured to the upper side of the plunger 26,,-the I member 231 ,being spring pressed upwardly and provided with an adjustingscrew and nut to regulate its dis tancefrom the member 230, and a circuit wire leading fromeach of the switch member's connects through a suitable source of power with an electric lamp 232 located on the front of. the machine in plain view of the operator. The adjusting screw connected to the member 231 will be set so that the' spring surrounding the set screw will keep the members 230 and 231 contact until the springs41have nearly reached the limit of their expansion after the plunger 26 has ceased to move upwardly. the contact between thejneembers 230 and 231 being broken almost simultaneously-with the ending of thevexpansion of springs 41. Con-' nected to the underside of the plunger 26 is one member 2340f a switch and opposite the contact member 234 is the other contact member 235' which is secured to the mside 232. Secured to the lower extr Lity of the screw 28 and extending laterally therefrom to a point in vertical 'alinement with, a switch 237 is a finger 239 whichds adapted to contact with the switch 237 when the screw is raised to the limit of its upward movement and to close the said switch indicating by the illumination of the lamp 238 that it has reached the limit of its upward movement. The switch members 230 and 231 are designed to contact at the first movement in an upward direction of the plunger 26, this movement being signaled to the operator, bythe lighting of the lamp 232. The switch members 234 and 235 are designed to contact when the'plunger 26 reaches the limit of its downward movement, this. being indicated by the lightin of the lamp 236. The lamp232 will pre erably be red, the lamp 236 white and the lamp 238 blue so that a glance will indicate to the operator the positionpf the plunger 26 at each operation of the machine. In Figs. 1 and 5 rollers 240 are shown mounted in the bottom of the compartment 14 and a slidable tray 241 made of heavy wire netting fastened to a frame, is adapted to rest upon the said" rollers in position to be slid back-- wardly and forwardly into and out of the said compartment. 1

Referring now to Figs. 1, 4, 5 and 18 a flexible container 245 preferably formed of paraffin treated. paper or the like is shown, the container is rectangular and is formed with a' reinforcing strip 246 of heavy paper or the like about its upper-edge. The bottom is likewise formed-of heavy paper and has a reinforcing strip 247 connecting it to the side walls. -A longitudinal strip 248 secured to the under side of the bottom of the container and thence upwardly along one side .exti=nds slightly above the top and terminates in a tap 249. I

- A substantiallyU-shaped carrier 25.0 'of the exact width to receive the container 245 is shown in Fig. 19. The upper ends of the said carrier are rolled, as at 251, to afford a means for gripping the said carrier to lift it. The containers 245 thus formed are collapsible when empty and are designed to be filled with ice cream by the ice cream manufacturer after the common method now employed in ice cream factories in filling caps,

2 6., the semi-frozen ice cream commonly known as slush is run into the container, which 1s placed m a square can and is'then placed in what is known as a hardening room, where thecontainer remains until the ice cream has frozen to the-desired hardness. It is then removed from the square can by the tab 249 and placed in one of the carriers 250 to be delivered to the retailer. As shown in the drawings my machine is designed to 'hold five of thesefive gallon containers. one being removed from its carsier and placed upon the secondary plunger 40 in the casting 17, the remaining four being left in the 1rre spective carriers and placed upon the sliding shelf in the storage compartment 14. A door 252 is provided to close-the entrance to the,

v said compartment 14. The door 18 is provided with 'an outwardly extending rod 254 and when. the said door 18 is raised into ver-- I tical position to close the open side of the casting l7,', the rod 254 projects outwardly to contact'with the inside of a door 255 which is arranged to closethe entranceto the coinpartment in whichthe casting 17 is located.

' It willthus be seen that when the door 255 is closed its pressure against the rod 254 will holdthe door 18 firmly in position effecting an air-tight joint with the casting 17. A door 256 is located in the top of my machine and; is adapted when opened to giveentrance I 20Qto the ice spaces. All of the doors 252, 255

and 256 are formed with the usual rabbeted edges commonly used on refrigerator and ice box doors, the said 'rabbeted edges fitting into similar rabbeting about the apertures which the doors are designed to close.

In the practical operation of my machine the lid 256 is raised and cracked ice and salt "is packed into the spaces designed for this purpose. The motor 85'is then set in motion "and through the worm 84 and worm gear 82 meshing therewith drives the pinion 66 counter clockwise. The pinion 65 meshing with the pinions 66 is in turn driven, rotating the worm. 59 in the direction of-the arrow Fig. 2. The operating handle 79 is then lifted to bring the rotating worm into mesh with the worm gear 57, which being fixed to the 7 same shaft on which the gear 52 is mounted then releases the operating handle 79 allow drives the gear 52 in the direction indicated by the arrow. The gear 52 meshing with the gear 51 causes the sprocket 49 to be driven clockwise and through the medium of the chain 50 and sprocket 47 drives the shaft 45, carrying the. pinion 46 to rotate the bevel gear 36, which gear being internally thread- .ed to fitthe screw 28 causes the said screw,

together with theplungers 26 and 40. to descend within the casing 17. When-the plunv ger 26 has reached the limit of its downward movement the members 234 and 235 of the switch contact, signaling to-the operator by the illuminating of the lamp 232, who

ing the worm 59 to be forced out of mesh by the roller 71 operating on the bracket 72 underthe tension of the spring 77. The door ,255 is thenswung open and-the door 18 then lowered'into the osition shown in Fig. 1,

- exposing the interior of thecasting 17 One of the containers 245 filled with unfiavored 1 ice cream is thenplaced'upon the secondary plunger'40, the door '18 closed and the door 255 swung against the rod 254 and latched.

'For the sake of argument we will assume that a customer desires to purchase 10 cents worth of chocolate ice cream. The clerk,

operating the machine will then first swing 'the handle above the'plate 108 bearingthe figure 10, that is the handle 105, about onefifth of a turn in the direction indicated by the arrow on Fig. 1. This operation of the handle 105 causes. the rod 109 attached levers 119, 126 and 96, throwing into engagement the members 99 and 101 of the clutch [thereto to move the disk at its rear endwhich 'movement of the disk rocks the bell crank and starting the rotation of the shaft 92 and v the springs 41, have completely depressed.

It will very often be'desirable to use-my machine in conjunction with factory flavored ice cream. When this is the case the containers 245 will be filled with flavored ice cream at the factory, the said containers be-. ing placed in the machine in the usual way.

It will, however,;be unnecessary to provide the shredding block when prefiav'oredice' cream is being used and I therefore substi tute a block shown in Figs. 10 and 11 in the drawings and indicated at 260. This block is adapted to fit in the same manner as the block 1 80, but has no hexagonal. tubing secured in its central aperture. The aperture 261 is'vof the same diameter asthe interior of the portion, 162 and the Sliding cut-ofi' 262 it will be seen is at right angles to the longitudinal axis of the worm -conveyor. A

plate 264 hinged at 265 tothe front of the cut-oil block is adapted to be secured in raised position by the spring latch 266. It

,will be noted that Itheaperture 267. through the hinged plate is frusto-conical with the larger diameterof the frustumon the frontside of the plate. A plurality of pins 268 securedabout the periphery of the aperture 267 are design d to a'ctyas guides for the ice '9! cream, whieh -with the use of this cut-off block will hefed from the machine in the form ofa eore with a central aperture therein formed by the shaft 160. Thecorehs it emergesfrom thecut-ofi' block will he supported by the pins 268, and when the operation of the machine has ceased at fer having fed the roper portion ofice creain out upon slide freely ofi' of the pins when the plate has been dropped forward to bring them into 1 15 a ertical position. If, however, the core should forany reason cling to the pins 268 when the plate 264 has been swung to drop it into the dish, the spring pressed plunger 269 fitted through asllding collar 270 on oneof the pins 268, can be forced into the core and held thus while the collar 270 is slid downwardly toward the outer end of the, pin 268. It will be seen that this will effectually force thecoreto be released by the pins .125 i ,and will then fall intoythe dish or other rc-.

ceptacle. The collar 270 will then be returned by the spring'27l. The core thus forn' ed may now either be served as plain I ice cream or in the form known as a sunthe ice cream -juices, preserves r the \like and it will be readily seen that the aperture formed dae this being. a dish prepared by coverin ith crushed fruits, frui t through the chre of ice creamby m ma chine is ideally adapted to be filled with the compartment 1 1 and by virtue of theshelf:

241 the containers can be readily slid from the storage compartment and the container holding the desired flavor, selected.

It 'will also be noted that the carrier 250 isthe only returnable equipment that-it is necessary for the manufacturer of ice cream to leave 'ith the retailer. It will of course be understood that the paper container when once collapsed, emptied andremoved from the machine is thrown away. It is therefore unnecessary for the manufacturer to leave expensive cans, packing tubs and the like. By reference to Fig. 4 of the drawings it'will be understood that the upward movement of the plunger 40 ceases at the line indicated at which is the point where the side walls of the casting 24 begin to taper inwardly so that each tlme the screw 28 is reversed to draw the plunger downwardly, the space above uhe'lipe C in the casting 24 and about the worm conveyer will be left packed solid withice cream. When a fresh container is placed in position upon the pl anger the space between the top of the container and the bottom of the ice cream left packed in the casting 24 will be filled with air when the door 18 has been closed and locked into position and. in order to expel this air the valve shown in enlarged detail in Fig. 13 and previously "descrlbed is provided. It will be noted that in open position the head of the valve extends into the path of upward movement of the filled container and remains in such position until the upper edge of one side of the container contacts with the inclined face presented by the head of the valve, forcing it closed against the tension of the spring 172 as the said container moves upwardly. It will .thus be seen that the valve will not be entirely closed until the top surface in the full container has contacted withthe bottom surfaceof the ice cream remaining in the casting 24, therefore preventing an air pocket forming in the ice cream when it is fed into the worm conveyer.

It will also be noted by reference to Fig. 4 that the portion of flheworm conveyer 10- and scraping it away from the inside of the said tube.

From the foregoing description of m machine it will be obvious that I handle t e ice cream in a thoroughly sanitary and cleanly manner, remove the possibility of ptomaine poisons forming through contact with the 'metal can of-acid fruit flavored ice cream.

The only place in my machine where the ice cream at any time comes in contact with. metal is the interior of the casting 24 and the Worm 161 and as set forth in these specifications a lining ofnon-corrosive metal is applied to the inside of the said casting and the worm conveyer 161 and its shaft 160 are either formed of non-corrosive metal or heavily lated with the same.

It wil also be apparent that in my machine the flavoring syrups will never come in contact with the air until the said air -has been purified by the air washing s stem,

thereby eliminating the possibility o dust,

foul air, etc, being sucked into the syrup containers to displace the syrup withdrawn. My method of handlingthe ice cream itself also eliminates the-unsanitary and uncleanly process of dipping into the can with a spoon or scoop, .WhlCh is generally kept in a receptacle filled with wash water,',,which waterbecomes filthy after a few mlliutes use and is entirely unfit to rinse utensils used for handling eatables. Another unsanitary feature-of dispensing mecrea'm, eliminated by my machme which-is always present with the use of the ordinary ice cream can is that! a the removal of the cover to the said can for the purpose of dipping out ice'cream will permit the foul air from the ice cream tub, the wood of which is very frequently in an advanced stage of decay, to enter the can and contaminate the ice cream therein.

Another decided advanta e gained by the use of my machine is that t e manufacturer of choice cream is no re uired to leave expensive cans, etc., wit t e retailer, whose clerks frequently misuse the said cans, permitting them to become battered and rendered unfit for further service. The only returnable equipment which the manufacturer leaves is the carrier 250 which can be formed of any chea ex ense to the manu acturer.

he brine circulating 5 Stem in my machine also makes ractical use of the brine;

sheet metal at little formed by the 'me ted ice and salt, which is usually drained from the packing tub under ordinary methods and run into the sewer.

A great saving is therefore efi'ected in the.

. 50% less icing is required than with the.

" 1. In a machine for dispensing ice 1 amount ofice to refrigerate a given amount of ice cream at the proper temperature as ordinary ice cream tubs. A big saving is also effected in the ice cream itself by pre-- venting it from coming in contact with the air as is the case when the ice cream'is kept in a can and dipped out. Actual test has proven thatthe 25% shrinkage which occurs when the can and tub system of storage is employed is entirely, eliminated with my machine.
